QUINCY (CBS) - A Quincy man was arrested Wednesday after he allegedly held his girlfriend against her will for a week and abused her. Matthew McAuliffe is charged with aggravated assault and battery, strangulation, and kidnapping.

Detectives say that the woman ultimately jumped from a second story window to try and escape. Witnesses saw her screaming for help and called police.

When officers arrived, neighbors told them a man had grabbed the woman and dragged her into an apartment. When police forced their way inside they found the woman unresponsive, along with 32-year-old McAuliffe.

The victim was taken to a Boston hospital. McAuliffe was arraigned in Quincy District Court on Thursday morning.

"We want to publicly commend the neighbors for getting involved," Quincy Police said in a written statement. "They did exactly what we would hope: they contacted 9-1-1 and observed from a safe location."

They added that the neighbors actions "may very well have saved this young woman's life."
